MattJackson 547babf39a Unified Stream trait: read() and write() on one type 
Stream trait: read() returns PesFrame, write() accepts PesFrame.
A stream is a stream — you read from it or write to it.
No separate Input/Output traits.

API: libfreemkv::input(url) and libfreemkv::output(url, title, codecs)
Returns Box<dyn Stream>.

MattJackson e33b13a7ca PES pipeline: InputStream on DiscStream + IsoStream, MkvOutputStream 
- DiscStream: next_frame() reads sectors → decrypts → demuxes → returns PesFrame
- IsoStream: same pattern, reads from ISO file
- MkvOutputStream: accepts PesFrame, writes MKV via MkvMuxer
- InputStream trait: next_frame(), info(), codec_private(), headers_ready()
- OutputStream trait: write_frame(), finish()
- FileSectorReader: SectorReader backed by a file
- PesFrame: track + pts + keyframe + data

Old Read/Write IOStream impls preserved for backward compatibility.
Next: replace pipe() in CLI to use PES pipeline.

MattJackson 6824f430d8 decrypt_sectors returns Result — fail instead of silent corruption 
Previously used all-zeros AES key when unit_key_idx was out of range,
producing silently corrupted output. Now returns DecryptFailed error.
Also wired --raw flag through InputOptions → set_raw() on streams.

MattJackson 119d09ed02 Wire --raw through InputOptions to streams 
set_raw() on IsoStream and DiscStream sets keys to None.
open_input passes raw flag to streams via InputOptions.
Streams skip decrypt when raw=true.

MattJackson 31ba60b66f Decrypt back in streams — streams handle their own decryption 
IsoStream decrypts in its read path using keys from scan.
IOStream trait gets keys() method with default DecryptKeys::None.
Pipeline no longer handles decrypt — just reads decrypted bytes.

MattJackson e82e869aa9 Add keys() to IOStream trait — streams know their own decrypt keys 
- IOStream::keys() default returns DecryptKeys::None
- IsoStream and DiscStream override with real AACS/CSS keys
- Pipeline calls input.keys() instead of separate scan_keys()
- Streams are self-contained: read bytes + provide keys

MattJackson cc84f954c2 Drive recovery, reset on open, simplified DiscStream 
- SgIoTransport::reset() — open/close/TUR/escalate on every open
- Drive::read() — single read method with error recovery (min speed,
  sleep 30s, retry, phase 1/2/3 escalation)
- Removed read_timeout, read_sectors, read_range — one read() method
- DiscStream simplified — no on_error/on_success/Recovery, delegates
  all error handling to Drive::read()
- IsoStream no longer decrypts — streams return raw bytes, pipeline
  handles decryption
- reset() on all platforms (Linux real, Windows/macOS stubs)
- Watchdog thread removed — kernel handles USB timeouts

MattJackson 9d63ff75e9 Doc comments, format string inlining, long literal separators 
- Doc comments on DriveSession, find_drives, all Error variants, Result type
- 24 format! strings inlined (clippy pedantic)
- 25 long hex literals with separators (0xFFFFFFFF → 0xFFFF_FFFF)
- README install example updated to 0.8

MattJackson a74d395f68 Audit v3 fixes: all 3 tiers (19 findings) 
Tier 1 (compilation + correctness):
- Fix nightly-only is_multiple_of → % 2 != 0 (stable Rust compat)
- Fix parse_sample_rate: check 192 before 96 (was returning wrong rate)
- macOS drive discovery: split unix.rs → linux.rs + macos.rs
- Linux: EACCES returns DevicePermission not DeviceNotFound
- CLI pipe.rs: Ctrl+C signal handler added

Tier 2 (correctness + security):
- MkvStream: reset demuxer after scanning→streaming transition
- Windows SPTI: zero data buffer before ioctl
- AACS cert verification: documented why silently skipped
- KEYDB: HOME + USERPROFILE fallback for Windows
- Library modules: pub(crate) for internal modules
- AACS: explicit re-exports, AES primitives pub(crate)

Tier 3 (performance + polish):
- IsoStream: batch 64-sector reads (was 1 sector at a time)
- DiscStream: buffer swap instead of copy in decrypt_and_buffer
- Vec capacity hints in TS/PS demuxer hot paths
- NetworkStream: TLS warning documented
- Batch rip: per-title progress display
- cargo fmt: 0 violations

319 tests, 0 fmt violations.

MattJackson c91d6e371f Chapters, DVD subtitle palette, MKV track flags, progress total_bytes 
Chapters:
- MPLS PlayList marks parsed (mark_type 1 = chapter)
- Chapter struct on DiscTitle (time_secs, name)
- MKV Chapters element with EditionEntry/ChapterAtom per mark
- 3 MPLS mark tests + 2 MKV chapter tests

DVD subtitle palette:
- IFO palette extraction (PGC offset 0xA4, 16 × YCbCr colors)
- YCbCr→RGB conversion for VobSub .idx format
- DvdSubParser codec_private returns formatted palette
- codec_data field on SubtitleStream flows through pipeline
- 5 palette tests (YCbCr conversion, formatting, overflow)

MKV track flags:
- FlagDefault: primary video/audio = 1, secondary = 0
- FlagForced: forced subtitles = 1
- Language: set from stream language code
- Already implemented, verified with 4 new tests

Progress total_bytes:
- IOStream trait: total_bytes() -> Option<u64>
- DiscStream, IsoStream: from disc_title.size_bytes
- M2tsStream, MkvStream: from file metadata on open
- NetworkStream, StdioStream, NullStream: None

316 tests total, all passing.

MattJackson 01235ff347 Audit fixes + DVD support foundation (IFO, PS demux, MPEG-2, CSS crack) 
Audit fixes (14 critical, 22 warnings):
- UDF: bounds checks on all ICB/FID parsing from disc data
- SCSI Linux: saturating_sub on residual, CDB length guard, buffer size guard
- SCSI macOS: SCSITaskStatus u32 (was u8 — stack corruption)
- AACS: EC mod_inv returns infinity instead of panic, key reduced mod n
- AACS: do_handshake tries all host certs (was returning on first failure)
- H.264: bounds check on SPS < 4 bytes
- ContentReader: error on missing unit key (was zero-fill)
- KEYDB: flat redirect loop (was recursive), 100MB response limit, Windows HOME fallback
- ISO writer: AVDP extent order, partition length, allocation cap
- Network: removed TCP_NODELAY on bulk stream
- MKV: guard on u64::MAX seek
- disc.rs: saturating_sub on extent offset, simplified dead region code
- cargo fmt (610 violations), cargo clippy --fix (55 auto-fixes)

DVD support (new files):
